Teeth Whitening Pen by Zero Peroxide, Natural Teeth Whitening Gel, Instant Professional Results, Made in USA, No Sensitivity, 2mL

This pen is working so well. Im not confident enough to post pictures yet as my teeth are still dingy, but they have gone from yellow to off white in a few uses. The solotions does not hurt my teeth either as past whiteners have. The applicator is wleasy to use and tastes pretty good. I cannot wait for white teeth again.

Easy to use and seems to work but the pen stopped advancing product after 1 week (barely 1/4 of the product used).I submitted a comment to the seller a few days ago asking if there is a way to fix it and have not heard back from them yet. If the pen had not stopped working I would have rated this 4 or 5 stars.

This is my second attempt with this pen. My disappointment is mostly with the fact that the product dispenses below the brush before it reaches the brush tip.

This whitening gel did a better job than other brands I've tried. The effect is the quickest I've found. I don't believe any whitening formula lives up to the promises it proclaims but this gel applied nicely and the results could be seen the next day. My teeth are not highly stained but I was able to see a difference. It also didn't cause my teeth to be overly sensitive after using like I've experienced with some other brands. I don't think the tub lasted along as I would have liked.

Was very excited to try this whitening pen as I have sensitive teeth, so I was specifically looking for something without peroxide. I’m not even sure that I want to try it now that it arrived though since it looks completely different than the original photos. The package also says “expires 1 year from ___” (left blank only because the barcode is covering this portion and I can’t get the sticker off). I don’t know if this pen is old or new or what’s going on with it. The gel on the inside looks a little murky too. May return, may wait to see if the seller contacts me for clarification on why my pen looks this way. Will update my review if so!

I got a white smile with a few clicks. The soft brush tip of this pen allows it to be easily applied to and around every tooth, so every stain on my teeth is clean. I am much happier now that I have regained my former beautiful smile.

Unfortunately this product did not work for me. I never saw any results; however, it may work for you. It is super easy to use and the flavor was fine.

I returned unused. It was not at all what I expected. I thought it was a type of temporary "paint" for instant in a pinch whitening
